UPDATE (11/13/17, 11:00 p.m. ET):Arrow star Stephen Amell and Legends of Tomorrow's Caity Lotz have now joined the chorus of voices speaking out about the sexual harassment allegations against executive producer Andrew Kreisberg.

Amell posted a thoughtful and candid video to his Facebook page on Monday (November 13), in which he not only addressed the studio's current investigation into the allegations ("if they need my help in any way, shape or form, they will get it") but also pledged to be a better ally to his cast and crew on set.

"Our biggest asset on Arrow is our crew, and furthermore, their biggest strength and our biggest strength is working as a team," he said. "I told them this morning, and I tell you now — and I meant it — that if anyone ever feels anything less than 100 percent safe, or anyone feels as though they aren’t allowed to express themselves and be the person that they are, that they should come to whomever they are supposed to go to and that I’ll stand right besides them, right behind them. I’ll speak on their behalf if need be."

Earlier, Lotz tweeted her support for the "brave women and men who are coming forward to condemn their abusers."

Candice Patton, who portrays Iris West on The Flash, tweeted that she stands in solidarity with her sisters "100%" However, she added that, understandably, she does not feel ready to "speak on the issue (and other issues) in a productive way" at the moment.

Supergirl star Chris Wood condemned the "industry-wide standard of stubborn and often angry sexism" in a passionate note posted to social media. He also took aim at those in positions of power who respond to these allegations with silence. "A responsibility that comes with having power is taking care of those who work for you," he wrote, "and I hope each person involved in tolerating this behavior is now reflecting on their decisions."

Late Friday evening (November 10), Warner Bros. Television Group suspended prolific television producer and showrunner Andrew Kreisberg amid allegations of sexual harassment. Kreisberg, who serves as co-showrunner on Supergirl and The Flash, as well as executive producer on Arrow and DC's Legends of Tomorrow, was the subject of a shocking Variety report in which 19 sources accused the producer of sexual misconduct and inappropriate physical contact in the workplace.

In the aftermath of the scandal, Supergirl'sMelissa Benoist and Chyler Leigh, as well as Arrow's Emily Bett Rickards, have all spoken out about "changing the norm" in Hollywood and the need for safe, respectful environments on set. Kreisberg is not addressed by name, but his alleged pattern of sexual harassment clearly weighs heavy on the cast and crew of his productions.

"I am a woman who leads a show that supports equality and feminism, empowerment, and fighting for what is right," Benoist shared on social media on Sunday night (November 12). "I have always tried to conduct myself this way personally, as well. Sadly, the show and my career are a part of an industry that doesn’t always mirror these sentiments."

Benoist concluded, "So this week, I'll head back to work on Supergirl even more committed to being a part of changing the norm by listening when people speak up, and refusing to accept an environment that is anything less than a safe, respectful and collaborative space."

Her Supergirl costar Leigh echoed her TV sister's sentiments on Instagram with a quote from Maya Angelou: "Each time a woman stands up for herself, without knowing it possibly, without claiming it, she stands up for all women." She then added, "Let's #CreateChange together."

Leigh also replied to Benoist's tweet with a simple yet powerful "love you Sis."

Shortly after Benoist's post, Rickards took to social media with her own statement in the wake of Kreisberg's suspension. "To the men who committed sexual harassment, who perpetuated rape culture, who turn a 'blind eye,' and complain about 'reverse sexism': You are weak and complicit," she tweeted.

"To the women who found the strength to speak up," she added, "to the women who supported one another and to the women finding their voice: You can. You are heroines."

Warner Bros. Television is currently conducting an internal investigation into the accusations against Kreisberg. Berlanti Productions, the production company behind Kreisberg's shows, released the following statement:

"We were recently made aware of some deeply troubling allegations regarding one of our showrunners. We have been encouraging and fully cooperating with the investigation into this by Warner Bros. There is nothing more important to us than the safety and well-being of our cast, crew, writers, producers and any staff. We do not tolerate harassment and are committed to doing everything we can to make an environment that’s safe to work in and safe to speak up about if it isn't."
